So what is the deal with A/UX anyways?
The year is 1983, and several Apple employees visit Brown University, and get some idea of what Universities want in a computer for the coming future. The big buzz of the era was the so called 3M machine:

Imaging mounted disk volumes under duress
Backups are critical. If you are lucky and organised you have a set of useful backup primitives, such as Point in Time snapshots on your Infrastructure As A Service (IaaS), your disk array controller, or volume manager. However there always seems to be some critical machine in my life that does not fall into these…

Reality Check for Cloudflare Wasm Workers and Rust
With native Rust support announced for Cloudflare Workers, one may be eager to jump in head first. I know I wanted to. However, I tested out a few use cases and found it too limiting. Either the desired APIs weren’t available, code size was too large, or the program couldn’t run within resource constraints. I remain…

PalmOS on Raspberry Pi
My PalmOS port is making progress on a desktop computer, with keyboard, mouse and a 1920×1080 monitor for display. While that was interesting, I wanted to try a different form factor, one tha…

60x speed-up of Linux “perf”
The tool is great, but it uses perf to record and analyze profile data, and perf on Debian has a performance problem : when not linked against libbfd , it shells out to addr2line for every address it needs to look up. Thousands and thousands and thousands of incredibly short-lived processes.

Linux implementation of Homa, a protocol to replace TCP for low-latency RPC
Programming note: I will be taking a several week break from writing paper reviews for the summer. When we come back, I will be finishing off the papers from Usenix ATC and OSDI , then moving on to the great upcoming conferences (my non-exhaustive list is here ). As always, feel free to reach out on Twitter with…

Fast Rust Builds
It's common knowledge that Rust code is slow to compile. But I have a strong gut feeling that most Rust code out there compiles much slower than it could.

The Future Needs Files
For many mobile users, files are like dinosaurs, a holdover from the bygone desktop era. Sure, they “work” but, they’re mostly there because, you know, ancient history. I’ve discussed this issue for the last 2 years and I usually get some version of “get over it grandpa”.

Latency Sneaks Up on You
As systems get big, people very reasonably start investing more in increasing efficiency and decreasing costs. That’s a good thing, for the business, for the environment, and often for the customer. Much of the time efficient systems have lower and more predictable latencies, and everybody enjoys lower and more…

Some Reasons to Measure
A question I get asked with some frequency is: why bother measuring X, why not build something instead? More bluntly, in a recent conversation with a newsletter author, his comment on some future measurement projects I wanted to do (in the same vein as other projects like keyboard vs. mouse , keyboard , terminal and…
